I tried but i suck at it. At first i tried to make it 8k but vtfedit wouldnt import it so i stuck with 4k. Resolution isnt the problem, it's the fact that i dont know how to work brushes. I may try to improve it though.

Very nice! I love that kinda beaten up and run down look, but also how it looks a little new, because when it was given to you, they just finished fixing it up. Very realistic. Great job on putting this together.
